United ritates Patent G" 3,045,309 FASTENING DEVICE Frank E. Johnson,Sr., Wilmington, Mass., assignor to Umted-Carr Fastener Corporation,Cambridge, Mass, a corporation of Delaware Filed Dec. 30, 1959, Ser. No.862,976 1 Claim. (Cl. 24-216) At present, the pearl material is heldwithin a metal frame of some geometric form, which frame detracts fromthe aesthetic value of the pearl as well as increasing cost.

Other objects of the invention will, in part, be obvious, and will, inpart, appear hereinafter.

In the drawing:

FIG. 1 is a top plan view of the button engaged with a prong ring;

FIG. 2 is a side elevation of the button before it is engaged with apronged ring;

FIG. 3 is a side elevation of the button partially engaged with a prongring;

FIG. 4 is a section taken on line 4-4 of FIG. 1; and

FIG. 5 is a section taken on line 5-5 of FIG. 3.

In the drawing there is shown a decorative fastener part 2 formed ofsome type of plastic or imitation pearl material, such as nylon,synpearl, salt or fresh water pearl or the like. The said decorativefastener part 2 cornprises a base portion 4 in the form of a disk whosecircumference 6 is arced to converge at a point outside the areaenclosed by said base portion 4 to form a neck portion 8. Thesaid neckportion 8 has a diameter less than said base portion 4 and is integralwith said base portion 4. A dome shaped cap 10 is in integralrelationship with said neck portion 8 and in spaced relationship withsaid base port-ion 4. The said cap 10 has a diameter greater than saidbase portion 4, so that from a view taken above said cap 10, both theneck portion 8 and the base portion 4 are not visible. From a sideelevation, the edge profile of the base portion 4 and the neck portion 8is the form of a reverse curve, as shown in FIG. 2, with the concaveportion adjacent the cap 10 and the convex portion at base portion 4.

A pronged ring 12 comprising gripping tangs 14 in right angle'integralrelationship with a base ring 16 and a set of support engaging prongs18. The said prongs 18 are triangular in form, having a terminal end 20in the shape of. an angle less than 90. The pronged ring 12 is old inthe fastener art and is adapted to pierce a piece of material. Thegripping tangs 14 are adapted to engage the button."

To engage the decorative fastener part 2 and the pronged ring 12, thebase portion 4 is placed in abutting relationship with the base ring 16within the area formed by the gripping tangs '14, as shown in FIGS. 4and 5.

3,045,309 Patented July 24, 1962 FIG. 3 illustrates the fact that thesupport engaging prongs 18, at this stage, remain in right anglerelationship with the base ring 12. The support engaging prongs 18 maynow be passed through a support 22 until the base ring 12 rests againstthe said support 22. A socket 24 having a retaining portion which may bein the form of a curled lip 28, as illustrated in FIG. 4 of the drawingand also disclosed in the patent to J. Blazej, US. Patent No. 2,262,442,can be engaged with the support engaging prongs 118 by driving thesupport engaging prongs 18 into the recess formed by the curled lip 28,as shown in FIG. 4. The support 22 may be of any fabric, such as wool,nylon, silk or cotton. A dished area may be formed in the base portion 4of the decorative part 2 to accommodate some of the-support material 22when the socket is engaged with a stud.

When the decorative fastener part 2 is viewed looking in an axialdirection at the cap 10, the only portion visible to the eye is the cap10 as shown in FIG. 1. To the applicants knowledge, there is nodecorative fastener part presently available commercially whichdiscloses a decorative snap fastener attaching device where thedecorative fastener part 2 is not enclosed in some form of visibleframe. The frame is objectionable in many applications because itdetracts aesthetically from the decorative fastener part; also, it mayreduce the launderability of the garment. Of some importance is the factthat, although applicants decorative fastener part does not require aframe in the usual sense of the word, it is still attachable by use ofautomatic attaching machines.

Since certain other obvious modifications may be made in this deviceWithout departing from the scope of the invention, it is intended thatall matter containedherein be interpreted in an illustrative and not ina limiting sense.

I claim:

A decorative snap fastener attaching device comprising, in combination,an attaching member having a cup-shaped portion and attaching means forattaching the device to a snap fastener member and a decorative insert,said cup-shaped portion having a wall, said Wall being formed ofgripping tangs in spaced relation with each other, said decorativeinsert having a cap portion and an annular holding portion having anedge profile in the form of a reverse curve thoughout itscircumferential surface providin g a concave neck portion and a convexbase portion, said engaging tangs being disposed in superposed abuttingrelationship with the convex base portion, said cap portion being oflarger diameter than said holding portion and said cup-shaped portion sothat it overlies them and conceals them when viewed from the top andwhen said device is in attached position.
